본 고안은 가공 송배전선을 지지물에 가설할때 사용되는 전주용 크로스 암에 관한 것으로 재질을 가볍고, 기계적 및 전기적 절연성이 우수한 강화플라스틱을 사용하므로서 전주 가설공사에 있어 크로스 암 접지 공사를 생략할 수 있고 조류등에 의한 순간 접촉 감전사고를 예방할 수 있는 것이며 별도의 크람프가 장착되어 전선가설작업을 간편하게 함에 주안점을 둔 것이다.The present invention relates to a cross pole for electric poles used when installing overhead transmission lines on a support. The use of reinforced plastics with light materials and excellent mechanical and electrical insulation can eliminate cross arm grounding in electric pole construction work. It is to prevent instantaneous electric shock accidents caused by birds, etc., and the special clamp is installed to make it easy to install the wires.
종래의 크로스 암은 완금 또는 경완금과 같이 철재류이기 때문에 장기간 사용하면 아연도금이 벗겨져 녹물이 흘러 외관이 미려하지 못하고 또한 조류등에 의한 순간 접촉감전사고로 인하여 정전사고를 유발시키는 등의 결점이 있었다.Conventional cross-arms are made of steel, such as hard or hard gold, so if they are used for a long time, the galvanized metal is peeled off and the rust flows out, and the appearance is not beautiful.
본 고안은 이와 같은 결점을 해결하기 위하여 고안된 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to solve such drawbacks and will be described in detail by the accompanying drawings as follows.
원통형의 본체(1) 중앙부에 2단 환상요철형의 절연대(2)(2')가 삽착 고정되고 절연대(2)(2')의 양측으로 다수의 관통공(3)(3')(3")을 뚫어 저면에 요돌면을 형성한 새들(4')의 구조를 가진 몸체(4)와 베이스(5)로 된 전선지지용 크람프(A)를 ''∩ "형 보울트(6)와 너트(7)로 장착하여서 된 것이다.A two-stage annular uneven insulator (2) (2 ') is inserted into and fixed to the center of the cylindrical body (1), and a plurality of through holes (3) (3') are provided on both sides of the insulator (2) (2 '). (3)) the wire support clamp (A) consisting of a body (4) and a base (5) having a structure of birds (4 ') having a concave-convex surface at the bottom of the `` ∩' 'type bolt (6). ) And nuts (7).
도면중 미설명부호 8은 가설전선, 9는 콘크리트 전주, 10은 전주 결착구멍, 11은 유수구멍(11')을 뚫은 양단캡, 12.12'는 고전압 및 위험표시 라벨을 표시한 것이다.In the drawings, reference numeral 8 denotes a temporary wire, 9 concrete poles, 10 pole pole binding holes, 11 both ends caps having drilled holes 11 ', and 12.12' high voltage and danger labeling.
이와 같은 본 고안은 원통형 크로스암의 본체(1)가 기계적 및 전기적 특성이 매우 우수한 절연체이므로 크로스암에 앉은 조류가 가설전선(8)에 접촉하여도 전도체인 콘크리트주(9)와의 사이에 전로가 구성되지않으므로서 근본적인 조해대책이 수립되어 순간 접촉 감전사고로 인한 정전사고가 예방되는 것이며 콘크리트 주의 고압및 특고압 배전선로의 크로스암 접지공사가 생략됨에 따라 소요경비를 대폭적으로 절감시킬수 있고 가설전선(8)을 크람프 베이스(5)와 몸체(4)내에 넣고 " ∩ "형 보울트(6)와 너트(7)로 간편하게 지지할 수 있는 것이며 이때 크람프 몸체(4) 저부에 요돌면을 형성한 새들(4')의 구조에 의하여 가설전선(8)이 더욱 견고하게 압착고정될 수 있는 것이다.Since the main body 1 of the cylindrical cross arm is an insulator having excellent mechanical and electrical properties, the present invention has a converter between the concrete column 9 which is a conductor even when a bird sitting on the cross arm contacts the temporary wire 8. Since it is not constructed, the fundamental damage control measures are established to prevent electrostatic accidents due to instantaneous contact electric shock accidents, and the cross-arm grounding work of high-voltage and extra-high voltage distribution lines for concrete can be omitted, greatly reducing the required expenses and installing temporary cables ( 8) can be easily inserted into the clamp base 5 and the body 4 and supported by a "∩" type bolt 6 and the nut 7. By the structure of the saddle (4 ') the temporary wire (8) can be more firmly fixed.
또한 원통형의 본체(1) 중앙부에 2단환상요철형의 절연대(2)(2')를 전주(9)에서 양쪽방향으로 삽착고장시켜 주수누설거리를 연장시켜 전기적성능을 더욱 향상시켰고 또한 활선작업시에 작업자가 절연대(2)(2')의 장해물로 인하여 가설전선(8)의 위험위치 즉, 전기적 안전거리를 넘어가지 못하도록 하였다.In addition, by inserting two-stage annular uneven insulator (2) (2 ') at the center of cylindrical body (1) in both directions from electric pole (9), it extends water leakage distance and improves electrical performance further. During operation, the operator was prevented from crossing the dangerous position of the temporary wire 8, that is, the electrical safety distance, due to the obstacle of the insulation stand 2, 2 '.
이와 같이 된 본 고안은 강화플라스틱의 비중이 여타제품보다 적어 무게가 가벼우므로 크로스암의 시공면이나 운반면에 있어 작업성이 좋으며 산업경제적인 측면에서도 우수하고 실용적인 고안이다.Since the present invention has a specific gravity of the reinforced plastic is less than other products, the weight is light, so the workability is good in the construction surface or the transport surface of the crossarm, and it is an excellent and practical design in terms of industrial economy.
